Vedclass · Answer

(C) Communities with a higher number of species are more stable as they can resist occasional disturbances.According to David Tilman's long-term ecosystem experiments,plots with more species showed less year-to-year variation in total biomass.Therefore,the Assertion is correct,but the Reason provided is scientifically inaccurate because higher species diversity leads to less variation in total biomass,not just 'animal' variation.

Assertion: Communities that comprise of more species tend to be more stable.
Reason: $A$ higher number of species results in less animal variation in total biomass.
